Sony isn't about to leave a big expanse of market that has been extremely successful occupied by NEX-6 and NEX-7. There will be an a7000 although with two announcements in a matter of weeks, I would expect Sony to pull back a little before making another. In fact, a6000 doesn't get to market until about end of March or early April.

The prediction about a focus on FE isn't far fetched, it is common sense. The APSc line is fairly mature and FF has only two models. If the AF system in a6000 works as advertised, and under a variety of conditions, the possibility of an Alpha 9 (aka a9) increases, above a7r.

Sure, there is a chance of lesser model under a7 as well but it will have to be stripped of features and I doubt that will be Sony's focus at this time. May be even EVFless or a more basic EVF, if not optional.
